The Fluke 41B Harmonics Analyzer combines the ease of use of a digital
multimeter, the visual feedback of an oscilloscope and the power of a harmonics
analyzer in a single instrument. If you're testing power on three-phase systems
or trouble-shooting harmonics on non-linear loads, no test tool makes it easier.
The Model 41B is ideal for further analyzing data and optimizing system
performance. Use the Fluke 41B's FlukeView® software (included) to download
acquired data to a printer or an MS-DOS® or Windows® compatible computer for
analysis and presentation.
Features at a Glance
Three Views of each reading
- Waveform
- Bargraph showing harmonic levels
- Numeric values
Real-time Display Updates
Display updates three times a second for a dynamic view of actual circuit
conditions.
Comprehensive Measurements
Measure rms, peak and total harmonic distortion (THD) for complex voltages
and currents - with no manual calculations required.
Three-Phase readings
From a simple single-phase measurement, automatically calculates three-phase
power for 3-wire balanced loads (typically 5% or less imbalance). To make the
single-phase measurement, simply connect the meter as shown and select the 3º,
3C watts display.
System Critical Data
Immediate readings of Power Factors, KVAR, Crest Factor, K-Factor.
Display Harmonics individually to the 31st
Min/Max and Average Recording
Data Storage
Up to eight complete measurement sets.
Isolated Serial Interface
Communications with a serial printer or DOS® or Windows®-compatible computer.
Safety Designed
To meet the latest standards: IEC 1010-1, pollution degree 2, Installation
Category III, material group II, 600 V. Double insulated protection as described
in IEC 1010-1, Annex H.
Volts
Display
One cycle of the fundamental waveform and its frequency. Instantaneous
voltage at cursor position.
Application
Identifying sources of harmonic currents. Obtaining data for designing,
specifying or sizing transformers, filters, etc.
Amperes
Display
%-fundamental or %-rms, rms value, frequency, and phase angle of fundamental
or harmonic currents (up to 31st), as selected by cursor from bar graph.
Application
Identifying sources of harmonic currents. Obtaining data for designing,
specifying or sizing transformers, filters, etc.
Watts
Display
Watts, volt-amps, power factor (total) and displacement power factor of
fundamental of single-phase or three-phase power.
Application
Identifying displacement versus total power-factor. Determining proper
power-factor correction methods.
